c)-0,6-(+2)-(0,3-1,8) =
d)-1,75-(0,6+1,2+1,05)=

Answer 1

a)

$1.65 + ( - 3.5) - ( - 2)$
$1.65 - 3.5 + 2$
$0.15$

b)

$- 1.5 - ( + 0.4) - ( - 0.32)$
$- 1.5 - 0.4 + 0.32$
$- 1.58$

c)

$- 0.6 - ( + 2) - (0.3 - 1.8)$
$- 0.6 - 2 - ( - 1.5)$
$- 0.6 - 2 + 1.5$
$- 1.1$
d)

$- 1.75 - (0.6 + 1.2 + 1.05)$
$- 1.75 - 2.85$
$- 4.6$
